JOHN MOORE, OF PROVIDENCE, RHODE ISLAND.

BUTTON OR STUD.

SPECIFICATION forming part of Letters Patent No. 278,724, dated June 5, 1883.

Application filed December 31, 1881. (No model.)

drawings making apart of the same, is a full,

clear, and exact description thereof.

Figure 1 shows my improved button with Fig. 2 is a section of post and shoe through the line m. Fig. 3 shows side and edge of post. Fig. 4 shows top and edge of spring. Fig. 5 is a view of the inner disk.

My invention relates to that class of buttons callec non-separable, and has for its object the production of a button which will be easier of adjustment and more nearly perfect in its operation than those now in use; and it consists in the construction and arrangement of the post, spring, and shoe, as hereinafter described.

In the drawings, A is the front of the button; B, the post; 0, the shoe; D, the spring, and E an inner disk. The post 0 is attached to the front A in the usual manner, and has at its outer enda slot, e, the sides of which project horizontally, partially closing the opening and forming lips f f. The spring D is raised in the middle, and the disk E is cut out to permit the bearing-surface of the spring to come in contact with the under side of the shoe 0. The disk E and the spring'D are retained in place by turning over the edge of the shoe 0.

In putting the several parts together the disk E is first placed in the shoe 0. The spring D, which is wider than the outlet to the slot 6, is then put through until the square lips or prongs ff rest in the raised or invertedo is attached to the front A. The lips f f are confined between the U -shaped spring and the narrow or connecting portion of the disk E. The sides of the U-shaped cavity are not exactly straight, but diverge slightly toward the shoe.

To insert the button the shoe is turned as in Figs. 1 and 2, and passed through the button-hole. This being done, suificient pressure is exerted upon the edge of the shoe by the finger to 1311111 or bring it to the position shown by the dotted lines, Fig. 2, which secures the button in place. The lips f f being square, and the place within which they are confined nearly so, it will be readily seen that the edges of the lips ff in turning, as the position of the shoe is changed in either direction, will raise the spring D, which will again find its contact with the next flat surface of the lips f f pre sented to it.

What I claim as my invention, and desire to secure by Letters Patent, is-

y In a button, the shoe 0, provided with the disk E, having its middle portion cut away, as shown, and the spring D, adapted to receive the end of the post, all substantially as shown and described.
